CALGARY, Alberta - By the time candles supposedly made from remains of a deceased ExxonMobil janitor named Reggie Watts were handed out, an audience of oil and gas professionals attending a keynote luncheon at Calgary’s Gas and Oil Exposition realized they’d been had.

A man named “S.K. Wolff,” claiming to be an analyst for the Washington-based National Petroleum Council, and co-speaker “Florian Osenberg,” said to represent ExxonMobil, were getting ready to show a memorial video made by Watts when security officers forcibly ushered the two men from the stage.

Wolff is really Andy Bichlbaum and Osenberg is Mike Bonanno — or so they say.

As the Yes Men, the pair have travelled the world with an anti-globalization agenda perpetrating hoaxes on groups ranging from the World Trade Organization to the BBC.
